Similarly, the jellyfish doesn't have a complete digestive system, lacking intestines, a liver, a pancreas in various other critical organs.

类似地，水母没有完整的消化系统，缺少肠道、肝脏和胰腺等重要器官。

When food is scarce, they divert nutrients towards the really critical organ, the brain, and away from other organs like the heart and liver.

当食物紧缺时，他们把营养留给最重要的器官——大脑，并减少其他器官，例如心脏和肝脏，的供给。
